Abstract: The Requirement Engineering (RE) is the most important phase of the software development life cycle (SDLC). This phase is used to translate the imprecise, incomplete needs and wishes of the potential users of software into complete, precise and formal specifications. The specifications act as the contract between the software users and the developers. Therefore the importance of Requirement Engineering is enormous to develop effective software and in reducing software errors at the early stage of the development of software. Since Requirement Engineering (RE) has great role in different stages of the SDLC, its consideration in software development is crucial. There exist a number of approaches for requirement engineering. Among the approaches, object-based and problem domain-based approaches are widely used. An effective analysis of methods is essential for the appropriate capturing of requirements. Taking the above viewpoint into account, this paper demonstrates an effective method of requirement engineering, which plays an important role in different phases of the SDLC. Hospital can be seen as an example of a complex system. Therefore, the paper considers Hospital as a case study for which a software system has been developed taking the mentioned approach into account.

Abstract: Future military and civilian unmanned systems will be extensively used on land, under the sea, in air, and in space. Evaluation of their autonomy is critical to realize the autonomous operation ability of unmanned systems. This paper discussed the basic concepts of autonomy and the significance of autonomy evaluation, and then surveys and describes existing evaluating methods. Based on analyses of key technologies and these technologies’ technical readiness levels, a cobweb evaluation model as a universal evaluation model has been used to evaluate unmanned systems. If the technology warps (aspects of autonomy) and wefts (levels of those aspects) of unmanned systems can be determined for the cobweb model, the model can handle the mutual coupling, high dimensions, and diversity of warp lines. This model potentially has wide application in evaluating various unmanned systems.

Abstract: Orthogonal frequency division multiplexing (OFDM) is a special case of multicarrier transmission where a single DataStream is transmitted over a number of lower rate subcarriers. In July 1998, the IEEE standardization group decided to select OFDM as the basis for their new 5-GHz standard aiming a range of data stream from 6 up to 54 Mbps. This new standard is the first one to use OFDM in packet-based communications. In wireless communication, concept of parallel transmission of symbols is used to achieve high throughput and better transmission quality. Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques for parallel transmission. The idea of OFDM is to split the total transmission bandwidth into a number of orthogonal subcarriers in order to transmit the symbols using these subcarriers in parallel. In this paper we will discuss the basics of OFDM techniques , role of OFDM in this era, its benefits and losses and also some of its application.

Abstract: This review article provides an overview of various novel nanowire array solar cells and highlights the aspects of electromagnetic simulations that are a valuable tool for understanding the optical processes leading to their distinct properties. As the computational methods commonly used for the task are well established, we focus on the question how numerical modeling can be used to assess the performance of a design and reveal the working principle of the devices. We conclude that scientific literature identifies numerical simulations as paramount for design and interpretation of experimental data.

Abstract: The designs of hydraulic turbines are usually close kept corporation secrets. Therefore, the possibility of innovation and co-operation between different academic institutions regarding a specific turbine geometry is difficult. A Ph.D.-project at the Waterpower Laboratory, NTNU, aim to design several model Pelton turbines where all measurements, simulations, the design strategy, design software in addition to the physical model will be available to the public. In the following paper a short description of the methods and the test rig that are to be utilized in the project are described. The design will be based on empirical data and NURBS will be used as the descriptive method for the turbine geometry. In addition CFX and SPH simulations will be included in the design process. Each turbine designed and produced in connection to this project will be based on the experience and knowledge gained from the previous designs. The first design will be based on the philosophy to keep a near constant relative velocity through the bucket.

Abstract: The degrees in Industrial Management are often so called combination degrees linking business and management to engineering.They aim to bring out the best of both worlds: to combine the logical, engineering mindset with economical and managerial awareness.Including the essentials and advanced knowledge of several fields in one degree program is a clear challenge.How to choose the essential knowledge and link it in a useful way?There is also a risk that the combination degree would produce just superficial engineers who would not be able to find their place in the world of work.This fear seems to be wrong according to a survey conducted for the graduates of [1995][1996][1997][1998][1999][2000][2001][2002] in Industrial Management at Lappeenranta University of Technology.One of the main reasons for the top-level employment of the graduates may be the smooth slide to the world of work through the master's thesis.The master's thesis reflects the whole curriculum and exposes the graduate's knowledge and skills, both in the academy and the world of work.

Abstract: Article history: Received 20 September 2011 Received in revised form November, 2, 2011 Accepted November, 18 2011 Available online 25 November 2011 In construction cost management system, normally earned value management (EVM) is applied as an efficient control approach in both status detection and estimation at completion (EAC) cost forecasting. The traditional approaches in EAC predictions normally extend the current situation of a project to the future by employing pervious performance factor. The proposed approach of this paper considers both qualitative and quantitative factors affecting the EAC prediction. The proposed approach of this research not only estimates the completion of the project, but also it can generate accurate forecast for the entire future periods using a fuzzy neural network model. The model is also implemented for a real-world case study and yields encouraging preliminary results. © 2012 Growing Science Ltd. All rights reserved

Abstract: SILVEIRA NETO, P. A. M. ; MACHADO, I. C. ; ALMEIDA, Eduardo Santana de ; CAVALCANTI, Yguaratã Cerqueira ; GARCIA, Vinicius Cardoso . An Experimental Study to Evaluate a SPL Architecture Regression Testing Approach. In: 13th International Conference on Information Reuse and Integration (IRI), 2012, Las Vegas. Proceedings of the 13th International Conference on Information Reuse and Integration (IRI). Los Alamitos, CA, USA: IEEE Computer Society Press, 2012. Abstract. In Software Product Line Engineering, where products are derived from a common platform, the reference architecture should be considered the main asset. In order to maintain its correctness and reliability after modifications, a regression testing approach based on architecture specification and code was developed. In this paper, we evaluate it in two different scenarios, the corrective scenario, in which it was performed after a corrective change in the code, and in the progressive scenario, executed after a evolution or enhancement, when some specification changes. The results showed that the progressive scenario was less costly than the corrective. Our evaluation also highlights the importance of a code-based technique to select a set of efficient and effective test cases.

Abstract: With growing interest in estimating true ability in contemporary learning, the demand for personalized learning and Web-based learning environments has become increasingly important. This paper develops a statistical and interpretable method of estimating ability. This method captures the succession of learning over time and provides an explainable interpretation of a statistical measurement, based on Item Response Theory and the quantiles of acquisition distributions. The results from the simulation and empirical study demonstrate that the estimated abilities can successfully recognize the actual abilities of students. The correlation values between the estimated abilities and the post-test score, which incorporate this testing history, are higher than values that only consider test responses at the time of testing. Furthermore, the pre-test and post-test administered to the experimental group show significant student improvement. These results suggest that this method serves as a successful alternative ability estimation and provides a better understanding of student competence.
